Error using sym, too many input arguments

So, I've been trying to solve this nonlinear complex 12x12 equation system

sym l2x l2y l3x l3y phi1 phi2 phi3 phi4 phi5 phi6 l1x l1y

Error using sym
Too many input arguments.

e1=l1x*(exp(-i*alfa(1))-1)+l2x*(exp(-i*phi1))-l3x*(exp(-i*rho(1))); 
e2=l1y*(exp(-i*alfa(1))-1)+l2y*(exp(-i*phi1))-l3y*(exp(-i*rho(1)));
e3=l1x*(exp(-i*alfa(2))-1)+l2x*(exp(-i*phi2))-l3x*(exp(-i*rho(2)));
e4=l1y*(exp(-i*alfa(2))-1)+l2y*(exp(-i*phi2))-l3y*(exp(-i*rho(2)));
e5=l1x*(exp(-i*alfa(3))-1)+l2x*(exp(-i*phi3))-l3x*(exp(-i*rho(3)));
e6=l1y*(exp(-i*alfa(3))-1)+l2y*(exp(-i*phi3))-l3y*(exp(-i*rho(3)));
e7=l1x*(exp(-i*alfa(4))-1)+l2x*(exp(-i*phi4))-l3x*(exp(-i*rho(4)));
e8=l1y*(exp(-i*alfa(4))-1)+l2y*(exp(-i*phi4))-l3y*(exp(-i*rho(4)));
e9=l1x*(exp(-i*alfa(5))-1)+l2x*(exp(-i*phi5))-l3x*(exp(-i*rho(5)));
e10=l1y*(exp(-i*alfa(5))-1)+l2y*(exp(-i*phi5))-l3y*(exp(-i*rho(5)));
e11=l1x*(exp(-i*alfa(6))-1)+l2x*(exp(-i*phi6))-l3x*(exp(-i*rho(6)));
e12=l1y*(exp(-i*alfa(6))-1)+l2y*(exp(-i*phi6))-l3y*(exp(-i*rho(6)));
result=solve(e1,e2,e3,e4,e5,e6,e7,e8,e9,e10,e11,e12)

Sadly I have an error, it says error usingSyms, too many input arguments

Here's the full code:

%Point imput and reference axis change

L=82.4;
L1=35.7;
L2=39.7;

for j=1:7
    PX(j)=Px(j);
    PY(j)=Py(j)-L;

end

for j=1:7

f = @(theta) [L1*cos(theta(1))+L2*cos(theta(2))-PX(j); L1*sin(theta(1))+L2*sin(theta(2))-PY(j)];

p=[0.24 0.245];
thetA=fsolve(f,p);


Theta1(j)=thetA(1);

Theta2_Grados(j)=360+Theta2(j)*(360/(2*3.141516))


end




for j=1:6

alfa(j)=Theta1(j+1)-Theta1(j);
rho(j)=alfa(j)+0.17;

[KSSV]

Replace sym with syms.

Instead of i (complex number) 1i is preferred.

[José David Castillo Blanco]

Hi, thanks, it solved it but the results were pure zeros

[Torsten]

Yes, it's a solution ...

[José David Castillo Blanco]

any way to get another solution?

[José David Castillo Blanco]

Digged a little about the command, inserted an initial guess, now I have another solution but apparently is on complex numbers which doesn't help me for my mechanism synthesis.

Thanks for the help anyways
